DNAT and PPTP
Hello, I''m trying to setup DNAT to forward to a PPTP Server behind Shorewall. I setup the PPTP rules per your documentation with tcp port 1723 and Protocol 47 DNAT to my PPTP Server in the local zone. Looking at the logs it is dropping the connection going to port 1723. It is also dropping UDP port 1701, don''t know if it is of any significance. I looked at FAQ 1a and b and the

Linux distros and PPTP passthrough
Any recommendations for a Linux distro to put Shorewall on top of? My main concern is to be able to use a Windows NT PPTP VPN server behind the firewall. If I remember right, there were some issues with passing GRE traffic through some versions of the Linux kernel. Are they solved now or do I still have to do some cryptic kernel patches? Experiences with that? Thanks! Tim

Proxy ARP and RH 7.2
I have tried unsuccessfully to run both Shorewall 1.2.x, 1.3.x with Proxy ARP on a Red Hat 7.2 machine. The machine was configured as the external firewall as per the ''belt and suspenders'' layout given at http://www.skippy.net/linux/firewall/ The firewall appeared to function correctly in all functions except proxy ARP, however I must say I did not test exhaustively.

Can I pass PPTP packets thru 2 firewalls?
Is it possible to pass PPTP packets through 2 firewalls before they hit the remote access server? I installed a Netgear ProSafe VPN firewall as the first line of defense in my network. I have since set up a Fedora Core 2 server running Shorewall 2.1.3 and Squid in non-transparent mode, between the Netgear unit and my network. So, the Netgear faces the Internet with a public, static, IP address.

Fw: VPN setup problem - proxy arp I think

DMZ hosts gateway
Hi everyone, I have a question regarding the default gateway for hosts on DMZ zone. I moved servers from parallel to the DMZ (outside the firewall, directly connected to I-net) to inside DMZ. The default gw for these servers was the DSL router(bridge) of my ISP. What should be the default gw (for the hosts inside the DMZ), when hosts are inside the DMZ now - still the DSL router (external

Shorewall DMZ - Proxy ARP or Static NAT
Hi All, >From the documentation I have read on Shorewall, the preferred approach seems to be, to use Proxy ARP instead of Static NAT for hosting web servers in the DMZ Zone. But I have also read that this could cause problems for VPN configurations. I essentially have multiple public IP''s, which I want to map to private addresses in the DMZ. I also intend to setup a gateway between 2
